The Node-RED flow implements the access to the weather API you can use during your CallForCode challenge. Here is what you need to do, to get... Continue Reading →

The reason for this is mostly that cors (cross-origin resource sharing) is not enabled for the Node-RED server. This blog post is a simple workaround for this problem. By the way, you can use...
